Applieation'filed June 15, 1920. Serial No. 389,226.

Patented Apr. 4, 1922.

To all whom it may concern:

Be it known that we, WALTER SNELLING and LrioNon HENRI BELLAVOINE, engineers, the first subject of the King of Great Britain, the second subject of the French Republic, residing at Paris, Department of the Seine, in France, and having post-office address 13 Quai Voltaire, in the said city, have invented certain new and useful Improve ments in Typographic Composing Machines, of which the following is a specification.

The present invention relates to typographic composing machines actuated by keys or manually and more particularly to machines in which a perforated paper strip is employed to ensure accuracy of register.

The invention has for its object to facilitate the composition of tables with multiple justification, so as to render the operation one that can be performed by any operator, to overcome the difiiculties heretofore experienced in the performance of this class of work, and to ensure the advantage of obtaining an output substantially equal to that obtained in the composition of continuous lines with single justification. V

In the art of typography a table may be defined as follows :-1ines of composition forming columns of dissimilar justification, disposed side by side and separated by a border line. i

In typography these columns are generally composed separately, composing machines in which registering strips are employed, as described for example in the specification of United States Letters Patent to Booth No; 1,079,326 of November 25, 1913, being employed to set up the associated lines horizontally.

The means at present employed for this purpose are very complicated and liable to frequent error and require a very thorough knowledge of the machine, and also sustained attention on the part of theoperator.

With a machine embodying the present invention, which has been contrived for application to the machine described in the specification of United States Letters Patent to Bancroft and Indahl #944,405 of Dec. 28, 1909, without, however, being limited in its application to this machine, it is impossible for the operator to make mistakes; the mechanism, which is very simple, is, apart from the tabular composition, absolutely independent of the operation of the machine; the

invention serves to disable or put outof operation the registering strip at the will of the operator, while permitting him to continue to employ the ems keys and those serving for justification.

The paper strip being out of operation, it is easy to change over from one justification to another as is required in the composition of a table having different columns, with the same certainty as in ordinary composition, and without loss of time.

The following is an example The operator having a model to compose representing a table comprising four columns (cylinder of 89;) i. e., 1st column ll; ciceros or 69 ems 5 units, 2nd column 5!; ciceros or 8 ems 5 units, 3rd column 15 ciceros or 22. ems 2 units, 4th column 6 ciceros or 9 ems 1 unit.

It will be necessary to take as the basis of justification the longest line, that is to say the third column with 221} ems, 2 units. This justification once effected, it will be necessary to determine the differences in ems and in units between each of the columns relatively to the third column. The operator will record these differences in writing inorder to have them under his eyes at the moment of changing from one justification to another. The countonce established,there is obtained the following differences between the first column and the third column 10%} ciceros 01:15, ems, 6 units. Between the secondwcolumn and third column 9%- ciceros or 14611186 units. Between the fourth column'and the third column 9 ciceros or 13%- ems 1 unit.- The machine being justified for 292,- ems 2. units the operator will pull the button Effor setting in movement the mechanism which is to disable the paper strip; he will then depress fifteen times successively the ems key, then once on the justification key bearing the numeral 13; the units wheel having operated without the paper being moved, the justification for the first column to be composed will be effected absolutely exactly; then the operator presses the button E in order to permit the liberation of the paper, then he composes the first column and justifies it like an ordinary line; then he composes the second column repeating what has been done for the first; taking account of the ascertained dif ference; then hecomposes the third column for its entire length; then he composes the fourth column taking account of the ascertained difference and justifies it while utilizing both justification wedges at the same time, this latter operation alone serving to determine the entry into the galley of the four columns represented on the first line of each.

In the accompanying drawings Fig. 1 represents the upper part of the mechanism for unrolling the aper registering strip of a composing mac ine to which the invention is adapted. Figure 2 represents the lower part of the mechanism for unrolling the paper above referred to with the apparatus for composing tables, seen from the side. Figure 3 is an elevation in section on the line 3-3 Fig. 4 with the operating button E. Figure 4 shows the apparatus fitted to the machine, the operating button E and the piston valve C being removed. The same reference characters denote the same parts in the several views.

A denotes the rod which is set in movement by a piston F yielding to the pressure of the fingers of the o erator on any key, such as those with whic any of the existing machines is equipped, to efiect the feeding movement of the paper strip in accordance with the action of the operator on the keys.

B denotes a lever actuated by a piston D to which it is connected and which forms part of the mechanism of this invention. The lever B is adapted to throw out of ac tion at the will of the operator the rod A at the moment when a change of justification is to be effected. According to circumstances the piston C controlled by the operating button E gives or withholds motive power to and from the piston D.

Claims: 1

1. A mechanism for permitting a change of justification in typographic composing machines actuated by keys for composing tables, and provided with winding and unwindin mechanism for a aper registering strip, the combination wit 1 the unwinding device of said paper feeding mechanism, of an auxiliary pressure controlled device for acting positivel anism to put t e same temporarily out of action at the moment of change of justification.

2. A mechanism for permitting a change on said unwinding mech-' strip, the combination with the unwinding I device of said paper feeding mechanism, of an auxiliary independently operated pres sure controlled device for acting positively on'said unwinding mechanism, for putting said unwinding mechanism temporarily out of action at the moment of change of justification.

3; A mechanism for permitting a change of justification in typographic composing machines actuated by keys for composing tables, and provided with winding and unwinding mechanism for a paper registering strip and an operating rod therefor, of an auxiliary pressure device for acting positively'on said operating rod for putting the unwinding mechanism temporarily out of action at the moment of change of justification, said pressure controlled device coinrisin a lever and a fluid iston in contact P a:

with one end of said lever the other end of said lever being associated with said 0 erating rod, and means for admitting aid to said piston for operating the lever to control the actions of saidrod.

4. A mechanism for permitting a change of justification in typographic composing machines actuated by keys for composing tables, and provided with winding and unwinding mechanism for a paper registering stri and an operating rod therefor, of an auxiliary pressure device for actin positively on said operating rod for putting the unwinding mechanism temporarily out of action at .the moment of change of justification, said pressure controlled device comrising a lever and a fluid piston in contact with one end of said lever the other end of said lever being associated with said operating rod, and a man-uallyoperated valve for admitting and exhausting the fluid to and I from said piston for operating said lever.
